  2. 1. Dynamic Access Control for Industrial Systems

    Author : Björn Leander; Hans Hansson; Aida Causevic; Sasikumar Punnekkat; Tomas Lindström; Marina Krotofil; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cybersecurity; Industrial Automation and Control Systems; Industry 4.0; Access Control; Computer Science; datavetenskap;

    Abstract : Industrial automation and control systems (IACS) are taking care of our most important infrastructures, providing electricity and clean water, producing medicine and food, along with many other services and products we take for granted. The continuous, safe, and secure operation of such systems are obviously of great importance. READ MORE

  4. 2. Insights from modeling renewable electricity systems and developing hydropower models

    Author : Hanna Ek Fälth; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; renewables; electricity systems; hydropower; nuclear; modeling; Europe; MENA; transmission; available land;

    Abstract : One strategy for reaching a carbon-neutral electricity system is a large-scale deployment of wind and solar power. However, electricity systems with high shares of wind and solar power rely on other technologies, e.g. READ MORE

  5. 3. Electrification of Road Transportation - Implications for the Electricity System

    Author : Maria Taljegård; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; highway E39; CO2 emissions; electric vehicle; electric road systems; energy system modelling; variable renewable electricity;

    Abstract : It is incumbent upon the transport sector to reduce its CO2 emissions by replacing fossil fuels with low-carbon alternatives. Suggested strategies include electrification of the road transport sector through the use of electric vehicles (EVs) with static charging, electric road systems (ERS), and the use of electricity to produce fuels.

  6. 4. Modelling interactions between distributed energy technologies and the centralised electricity supply system

    Author : Joel Goop; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy systems modelling; variable renewables; power systems; distributed generation; demand response; electricity storage;

    Abstract : Renewable electricity generators, such as solar photovoltaics (PVs), and variation management technologies, such as battery storage and demand response (DR) systems, can be deployed in a distributed fashion, which can benefit the overall system. Such distributed energy technologies interact with and influence the centralised generation and transmission systems. READ MORE

  7. 5. Uncertainty modeling for load flow and hosting capacity analysis of urban electricity distribution systems

    Author : Umar Hanif Ramadhani; Joakim Widén; Joakim Munkhammar; Bri-Mathias Hodge; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Uncertainty model; Photovoltaics; Electric vehicle; Residential buildings; Hosting capacity; Probabilistic load flow; Electricity distribution systems; Urban Energy Systems; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

    Abstract : Urban demographics are changing, with more than half of the global population currently residing in urban areas. Traditionally, cities are often seen as passive energy consumers relying on external centralized systems. Motivated by the need to mitigate climate change, a shift is underway as cities actively shape energy systems. READ MORE
